Description

Hair dyeing equipment

The present invention relates generally to a hair dyeing apparatus, and more particularly to such an apparatus including a set of reciprocating hair dyeing and dispensing nozzles.

Domestic hair dye sets, including brushes and other accessories, are widely used in homes where home users typically achieve hair dye changes or cover unwanted gray areas. This allows the home user to dye his hair, but such a hair dye set has some known disadvantages. First, 5 minutes for hair dyeing, 5 to 30 minutes for hair dyeing first, 10 to 30 minutes for hair dyeing, and then about 5 to 5 minutes for the remaining hair to stain remaining hair from hair follicle to hair end. A longer time of the entire time, even 50-70 minutes, or even longer depending on hair length, to achieve dyeing, including at least 10 minutes until full-pull-through and subsequent hair cleaning is possible .

In addition, home hair dyeing is often a messy process for both color application and cleaning. All individual components and accessories of the set must then be discarded carefully.

Moreover, it is often difficult to achieve uniformity of color coverage of the hair, and the end result is often dissatisfied when compared to professional application, particularly by skilled stylists.

Accordingly, the present invention is directed to solving one or more of the above-mentioned disadvantages.

Thus, the apparatus comprises a handle; A cosmetic composition delivery system supported within the handle; CLAIMS What is claimed is: 1. A nozzle assembly comprising: a nozzle assembly including a nozzle array, the nozzle array including a plurality of nozzles guided distally therethrough; And a motor that moves the nozzle array, reciprocates back and forth, and delivers the cosmetic composition when the device is pulled through the hair by the user.

Home hair dyeing involves two treatment steps. In the first step, hair roots are processed, and color development time is continued. In a second step, the hair from the hair root to the hair ends is treated, which are referred to as hair follicle treatments and end treatments, respectively.

The apparatus of the present invention comprises a handle on which a hair dyeing system is located. The dyeing system is shown in block diagram form in FIG. The system, generally designated by reference numeral 10, includes a collapsible reservoir 12 for the selected color and a collapsible reservoir 14 for the developer. The reservoirs each have a closure part (16, 18) which is open during use of the appliance.

The apparatus includes a wall battery charger 20 connected to a charging connector assembly 22 whose output is connected to a controller 24 having a mechanism on / The mechanism operates as a battery 28 that is charged when the charger is plugged into the wall. The controller for operating the mechanism is connected to the motor 30 and the motor is connected to the rotor fluid pump 32 via the gear reducer 31 and the coupling 33 and the rotor fluid pump is connected to a fluid line 16 , 18 are connected. The rotor pump moves the fluid to the fluid combiner 38 and then to the static mixer 40 located outside of the nozzle assembly 42 in the illustrated embodiment.

In the illustrated embodiment, the nozzle assembly 42 includes a static (non-moving) frame or base 44. In the frame 44, a nozzle array 56 is movably supported. The movement of the nozzle array is achieved by the scotch yoke slot and pin arrangement 57, which moves the nozzle array back and forth in a reciprocating manner over a selected distance, i.e. amplitude, during operation. The rotor / pump structure is shown in detail in FIG. In Fig. 2, the lines from the color reservoir and the developer reservoir are shown at 46 and 48, which lead to a nozzle array 56. The rotor / pump rotates as shown (FIG. 2) and cooperates with the scotch yoke slot and pin arrangement 57 (FIG. 1) to cause the nozzle array 56 to move horizontally as shown in FIG. The nozzle array includes a plurality of, typically four, individual nozzles 58, 60, 62 and 64. One embodiment of a nozzle array is shown in greater detail in FIG. The dyeing material and developer are directed to the nozzle array by flexible pump tubes 67, 69 through the upper portion of the openings 68 and 70 of the array and mixed by the static mixer 72 in the upper portion of the array. The array is sealed at its periphery 71 at the nozzle frame. The seal can be welded or adhesive or hermetically sealed. The scotch yoke extension is shown at 73. The mixed color / color developer is directed to the lower portion of the upper portion of the array and through the individual nozzles 74, 76, 78 and 80.

Referring again to FIG. 1, the movable nozzle array 56 is located in the nozzle frame or base 44. There is a set or lines 84-84 of filaments that extend downwardly from the nozzle base on both sides of the nozzle line and on the side of the nozzle. The filament is located on the side of the nozzle array where the nozzle base 44 remains stationary and moves during operation. The filaments isolate or accommodate the hair between the filaments. In the illustrated embodiment, the filament is a conventional brush filament similar to a hair brush or comb. In the illustrated embodiment, the filament has a ball end with a radius of less than 1 mm, but the ball end is not essential. The filaments extend below the lower edge of the nozzle by a distance of about 0.050 inches in the illustrated embodiment to provide spacing for the nozzles from the scalp when the ends of the filaments contact the scalp during operation.

Figure 4 shows a cross-section of the nozzle assembly. It shows frame / base member 90 and one nozzle 92. The nozzles are connected to a channel 93 that leads from the dye and developer pump tubes (back and forth to each other) to the static mixer 95. On the side surface of the nozzle are two filaments 94, 96 on both sides of the nozzle. While filaments on opposing lateral sides of the nozzle are preferred, it is possible to use a filament only on one side of the nozzle, or, in some cases, the filament can be removed. As previously described, this arrangement is used to stain hair roots from the scalp, about the first 1 cm of the hair. The spacing between successive individual nozzles is important for the amplitude of the movement of the moving nozzle portion. The amplitude should not be less than the center-to-center nozzle spacing as noted above. To obtain full coverage, the amplitude may be somewhat larger. Also, as described above, in the illustrated embodiment, the filaments extend under the nozzle to ensure that the scalp does not come in contact with the moving nozzle, which leads to excessive absorption of the dye / developer mixture by stimulation and scalp .

FIG. 5 illustrates an alternative pump / mixer / scotch yoke arrangement, generally shown at 98. Which includes a molded tube assembly 99, a rotor 100 and a roller 101A assembly from a dye and developer reservoir, the roller assembly comprising a plurality of nozzles 104, And rotates with respect to tubes 101 and 102. The nozzle is formed on the side surface by the filament 105 of the fixed case. The nozzle array is moved from the rotor 11 by the scarf yoke including the drive pin 107 and the yoke slot 106 to move the nozzle array back and forth on the shuttle 106. [

Figures 7-9 illustrate the use of a device to pull hair through the scalp from front to back to stain the hair roots. The nozzle array typically moves left and right with an amplitude within a range of about 5 mm to 10 mm peak-to-peak, preferably 10 mm from the front edge of the scalp. The instrument is pulled from the front to the back of the head along the scalp, resulting in dyeing hair roots up to about 1 cm, and various brushing motors can be successfully used. Once the initial (first) pass is made, the instrument is moved back to the front edge of the scalp and moved back along the scalp. This occurs until the entire scalp is covered, resulting in staining of all hair follicles and usually requires 6-8 consecutive passes.

In some cases, as shown in Figure 9, the filaments are not positioned perpendicular to the scalp. Normally, the user can not expect to keep the brush head always perpendicular to the scalp. The maximum angle of acceptable error is typically 20 DEG out of the vertical.

Another factor affecting the length of hair dyed in the root region is the capillary action of the hue mixture in the hair. The capillary action of the staining fluid increases the length of effectively stained hair in the hair follicle. The additional length exceeding the average 1 ㎝ coverage depends on the amount of material applied, which is determined by the pump speed divided by the brushing speed and other factors. One approximation is 20% extra length of dyed hair.

Another factor affecting the length of hair that is effectively stained in the hair follicle array is the compression of the hair pressing firmly together. In general, if the nozzles are too short, the hair is compressed and the length of the treatment to the hair follicle is affected, covering all or most of the hair length, not just the hair follicle. Typically, in the illustrated embodiment, the distance from the nozzle tip to the nozzle base, i.e. nozzle length, is about 0.65 inches to avoid compression of the hair, but this can be varied to some extent.

In addition, the percentage of open area between the nozzles is important given the ease of use of the apparatus. Similar to the comb, the percentage of open area between successive nozzles in the illustrated embodiment is about 50%, which can be increased somewhat. The same open area requirement applies for filaments.

The bores of the individual nozzles may also be important for the cleanliness of the use of the apparatus. The low pressure drop across each nozzle limits the pump pressure requirements and also ensures that the residual pressure of the nozzle when the pump is started does not cause continuous dropping of the mixed dyeing material. In general, the minimum bore diameter of the nozzle is 0.060 inches. It is also understood that the bore diameter should gradually increase along the nozzle array, the minimum diameter should be closest to the fluid inlet, and the maximum diameter should be at the other end of the nozzle array. In one embodiment, the diameter of the nozzle at the inlet end is 0.065 inches and the diameter of the continuous nozzle is 0.070 inches, 0.075 inches, and 0.080 inches. However, these measurements may vary depending on the design application and the diameter is chosen to tend to equalize the material discharged from each nozzle.

In the illustrated embodiment, the wall thickness using polypropylene is typically 0.035 inches.

Finally, with respect to the motion of the nozzle array, the oscillation frequency must be high enough to cause overlap of the direction of motion of the brush as it moves through the hair. The user typically moves the brush slowly through the hair carefully, with an average speed of 2 cm per second. Although 300 Hz is used in this arrangement, it is more preferable that the frequency is 400 +/- 40 Hz. To achieve adequate coverage, the appropriate frequency determination is to divide the brushing speed by the nozzle diameter. In one example, when the outer nozzle diameter is 3.4 mm and the brushing speed is 2 cm per second, the resulting frequency is 400 RPM. However, the frequency may be higher depending on the particular application. Generally, the lowest comfortable operating frequency that provides the desired result is selected.

Figure 6 shows another embodiment of a nozzle assembly. The nozzle assembly includes a plurality of filaments, typically four filaments 92-92, on both lateral sides of a centrally moveable nozzle array 94 that are moved by an extension 96 from the scotch yoke, (90). The material is provided at the inlet 98 by the pump system, mixed by the static mixer 100, and then provided to several inline nozzles through the channels 102-102.

Following dyeing of the hair roots, the length of the hair from the hair root to the termination (end) of the hair is achieved. The second stage of hair dyeing is sometimes known as pull-out. Additional material must be applied to the hair to successfully pull-out to the very end of the hair. In the arrangement of Figs. 10-12, the nozzle is covered by end attachment 110. Fig. In the illustrated embodiment, the end attachments are fitted over the nozzles and held between the filaments, allowing the dye material to enter openings 112-112 between successive end members 111-111. The openings 112-112 are 4 mm wide and 9 mm high. In operation, the attachment 110 vibrates with the nozzle array with the end directly in contact with the scalp. The end member has a gentle radius, i.e., about 1 mm, as the end portion is slid relative to the scalp. In use, the device with the attachment in place is pulled through the hair all the way to the end of the hair 113. The hair color material and hair trapped in the attachment opening are shown at 114.

The volume of fluid used in the illustrated embodiment for each packet of dye and developer is about 60 cc, which can be varied. In the illustrated embodiment, the single pump rate flow is 10 cc per minute for the developer and 10 cc per minute for the dye. Flow is a function of viscosity as well as other fluid factors. The formulation provided in the packet for use with the instrument is adjusted for the pump flow rate and for the relative volume of each fluid.

The device may deliver a variety of cosmetic compositions, including hair dyeing compositions, hair treatment compositions, scalp treatment compositions and hair removal treatment compositions. The compositions include, but are not limited to, the following: hair treatment compositions such as a dye, conditioner, gel, glue, mousse, pomade, serum, tonic, wax; Scalp treatment compositions, such as dandruff treatment compositions, dry scalp treatment compositions, sunscreen compositions; A minoxidil composition comprising a depilatory treatment composition such as 6-piperidin-1-ylpyrimidine-2,4-diamine 3-oxide; Shampoo oils, such as Moroccan oil; Antifungal agents, topical steroids, anti-parasitic compositions, this treatment composition, etc .; Seborrheic dermatitis, psoriasis, head lice, white fungi, hair loss treatments, and the like; Cleansing treatments, styling treatments and conditioning treatments.
